IMPROVEMENT IN S'HINGLE-MACHINES.

Specification forming part of Letters Patent No. 162,988 dated May 4,1875; application filed February 20, 1874.

To all whom it may concern:

Be it known that I, ORRILLIUS T. WIL- LIAMS, of Smithland, in the countyof Livingston and State of Kentucky, have invented certain Improvementsin Shin gle-Machines, of which the following is a specification:

The nature of my invention consists mainly in the employment of areciprocating carriage carrying a fixed frow and knife for shaving andsplitting a board of even thickness from a stick of timber, and a pairof knives which are moved toward and from each other as the carriagemoves to and fro, and shape the board taken off by the frow and firstknife into a shingle of proper tapering form. My invention furtherconsists of certain hereinafter fully explained automatic mechanism forthe proper discharge of the shingles and the shav- 1n gs.

In the annexed drawing, Figure 1 is a plan view of my improvedshingle-machine. Fig.

. 2 is a vertical longitudinal section of the same.

Fig. 3 is a plan view of a portion of the carriage and the shears uponwhich the said earriage travels, exhibiting the stationary or fixedcross-bar that holds the board being split from the stick of wood. Fig.4: is a transverse vertical section through the receiver of thecarriage, exhibiting the throwing device. Fig. 5 is a longitudinalvertical section through the tapering knives, frow, and push-bar,showing the inner side of one of the shears having the converging way,there being two used in the machine to form the pattern. Fig. 6 is avertical transverse section of the tapering knives and the shears. Fig.7 is a perspective view of the push-bar, detached from the machine.

The same letters of reference are used in all the figures in thedesignation of identical parts.

The several working parts of the machine are mounted on a suitableframe-work, combining, in its construction, the shears A, upon which thecarriage B moves, being reciprocated through the medium of crank andconnecting-rods driven by gearing, in the manner clearly shown; Thesticks or blocks of timber to be worked up into shingles are placedbetween the slides (J of the adjustable crossheads 0 and G which aresupported in an elevated position over the carriage by fixed paralleland horizontally-arranged rods D. The cross-heads, after properadjustment with reference to the length of the sticks of timber, areheld in place rigidly by nuts (I on the screw-threaded portions of therods D. The sticks of timber feed down by their own gravity, beingarrested by the bottom plates B of the carriage, and the adjustment ofthe crosshead Oshould be such that the end of the stick abutting on itsslide 0 will be in line with the forward edge of the fixed crossar E,which extends from one shear to the other across the bottom plate of thecarriage, and toward which the knives travel in splitting and shavingthe shingles. This cross-bar E thus forms an abutment, giving the properend support to the stick directly in line with the path of the knivesand the frow, which frow and one of the said knives pass beyond it,above and below, respectively, while the 'two remaining knives bring upagainst its edge. The frow F and the knife F placed below and paralleltherewith, are fixed to the carriage, the frow-'which merely splits aboard from the under side of the stick-'-beingarranged slightly inadvance of the said knife, which has a sharp edge to take a shaving orthe unevenness from the bottom of the stick.

To permit the discharge or escape of the shaving thus cut throughbetween this knife and the bottom plate of the carriage, a transversespace or opening, f, is provided at this juncture. The said bottom plateof the carriage is hung on a hinge, b, so arranged with reference to thefixed cross-bar E, that at the full return-stroke of the carriage thehinge will, in practice, be back of the cross-bar. The object of hingingthe said bottomplate is to enable it to tilt or yield downwardly, forthe purpose hereinafter explained. The bottom plate of the carriage iscaused to yield or tilt downwardly by the action of the frow F upon theboard being split from the block or stick of wood, to permit the latterto pass below and be cut by the knife F, and also to enlarge the spaceor opening between such knife and bottom plate, to make room for theexit of any extra thickness of shaving or un evenness of surface thatmay be cut from the stick or block of wood. The said bottom plate isreturned to its horizontal position by means of a weight, I), in whichposition it is held sufficiently long to properly support the stick orblock of timber before the frow and knife begin to operate upon it ateach forward movement. After that the stick is held by the action of thefrow and knives pressing it forcibly against the cross-bar E, so thatthe bottom plate can then be tilted, as stated, without detriment to theoperation of the machine.

The shaping-knives G G, which are provided at their ends withright-angular plates or bars 9 g, having projections or lugs g g fittingor entering grooves or channels g in the inner sides of the shears, areguided in their movements by ways a a, they being brought in contacttherewith, and the grooves g 9 in which they travel, made to conform inshape to that of the said ways, which may be converging, curved, orparallel, or of other shape to form the pattern for the article to bemade.

The pattern, in practice, is permanently fastened to the inner sides ofthe shears, and is made of steel. These knives are slightly concaved andare arranged, in rear of the frow F and knife F, between the carriage Band the receiver H, by which they, the said knives, are confined inplace, so that they will be prevented from having independentlongitudinal motion. The shaving; cut by the lower shaping-knife isdischarged by its own gravity underneath the machine. The shaving cut bythe upper shaping-knife passes over said knife onto the plate I,underneath the covering-plate I of the receiver H, and is properlycleared from the knife during the return of the carriage and receiver bya push-- bar, K, which is attached thereto, but has imparted to it alimited independent reciprocating motion, during each return stroke. Ithas the form of a yoke, and, when at rest, its cross-bar extends acrossthe carriage just in advance of the upper shaping-knife. As this cutsoff the shaving, at which time the carriage has completed its forwardstroke, the said crossbar drops slightly, it being free to move to alimited extent up and down, so as to bring it directly opposite, thebutt end of the shaving being thus cut. The arms or rods of thispush-bar are respectively pivoted to the vertical arms of thebell-cranks L, fulcrumed on the carriage. The ends of the horizontalarms of these bell-cranks are connected by a rod, L the projecting endsof which extend into and travel in ways or grooves L in the frame.During the forward stroke of the carriage the rod L moves alonghorizontally, passing, near the end of the stroke, under and beyond theautomatic switches L which, as the rod escapes from under them, arethrown down by the inclines L.

On the return stroke of the carriage and its adjuncts, the ends of therod L are forced to travel over the curved back of the switches, wherebythe bell-cranks are operated, so as to give a limited reciprocation tothe yoke, which, in turn, strikes the end of the shaving and pushes itback off of the knife, and then returns to its original position. Theseshavings pass out over the end of the receiver. The shingles arereceived in the gutter M of the receiver, from which they are dischargedby means of an oscillating fork, N, the prongs n of which play throughslots m in the gutter. The fork is pivoted to downwardly-projectin garms of the receiver H, and carries in angular cars a a rod, N, theprojecting ends of which travel in cam-grooves N in the rear standardsof the frame, through which means the fork is oscillated at the propertimes, during which movement the prongs a rise through the gutter andtake hold of the shingle therein. As the shaping-knives cut close up tothe fixed cross-bar E it is advisable to cover or furnish the edge ofthe latter with soft meta-l, so that the knives may not be dulled incase a contact results. The plate 1 has an inclination equal to that ofthe upper surface of the splitting-frow F, of which it is a continuationand with which it is flush. It passes between the board being split bythe frow F and the main body of the stick of timber, and by bearing thelatter up, by reason of its inclination, facilitates the action of thesplittingfrow.

Although I have stated that this machine is for forming tapering orconvergent shaped articles of wood, as shingles, still it can be used informing curved and parallel or other desired shaped surfaces, such asbarrel heads and staves and the like, by substituting in lieu of theways shown those of the required shape.
